“…This dormancy can be overcome by exposing the seeds to light and cool or alternating cool and warm temperatures 3,4 . Low temperature seems to favour germination by promoting the breakdown of reserve proteins in the seeds releasing particular amino acids which are necessary for the growth of the embryo 5,6 . Pre-sowing treatments have been used to enhance seed germination of several wild-sourced medicinal plants of the Himalayan region 1,[7][8][9] .…”

Background and Objective: Heracleum candicans belongs to the family apiaceae. In Kashmir Himalaya, this plant grows at an altitude of 1700-5000 masl. The present study was carried out to enhance seed germination using different physical, chemical and hormonal treatments. Materials and Methods: For germination studies, seeds were subjected to different physical, chemical and hormonal treatments. Seeds were surface sterilised with 2% aqueous sodium hypochlorite (Hi-Media) for 5-10 min. The disinfected seeds were placed in sterilized Petri plates containing sterilized absorbent cotton moistened with 10 mL of treatment solution. Statistical analysis was carried out using SPSS (Version 22.0) statistical software and the results were examined according to Tukey's test. Different letters on the values indicate that the means are significantly (p<0.05) different. Results: Among the physical treatments, wet chilling at 4EC for 20 days proved to be most effective for seed germination. Among the three chemical treatments used, sodium hypochlorite treatment proved to be effective. Conclusion: Among the two hormonal treatments used, kinetin showed effectiveness in breaking seed dormancy as compared with GA 3 .

The effects of gibberellic acid and potassium nitrate on seed emergence and seedling growth of amaranth and Cleome gynandra were investigated in the greenhouse at Marondera University of Agricultural Sciences and Technology. The study was laid out in a factorial layout within a completely randomized design replicated three times. Potassium nitrate (dry seeds, 0.1%, 0.2%, 0.3%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, and 1%) and gibberellic acid (dry seeds, 100, 200, 300, 400, 500, 600, 700, 800, 900, and 1000 parts per million) were used, respectively. A total of 100 seeds of both crops were planted in each plastic pocket. Seed emergence percentage and vigor index of amaranth and C. gynandra were evaluated. The effects were more pronounced in seeds treated with gibberellic acid than in potassium nitrate. Seed emergence and vigor index of amaranth and C. gynandra seeds treated with gibberellic acid showed a significant difference at p < 0.01, while potassium nitrate showed no significant difference at p > 0.05. The maximum seed emergence percentage of amaranth and C. gynandra was 67.1% and 64.8%, which was obtained in 2022 and 2021, while the lowest was 35.5% and 37.5%, which was obtained in 2021. The highest vigor index I of amaranth and C. gynandrawas 590.3 and 586.2, which was observed in 2022 and 2021, while the lowest vigor index I was 45.2 and 170, which was obtained in 2021 and 2022. The results obtained indicated that the application of gibberellic acid on seeds of amaranth and C. gynandra can alleviate seed dormancy.
